            "description": "Hi, this is a quite strange tournament. \n\nFirst: it's FAST correspondence. \nFischer: clock starts with 2 days and increments by 12 hours per move up to a maximum of 2 days. This means that in the worst case, when your opponent uses no time to respond, you must be able to play at least two moves each day. \nBeware of timeouts!\n\nSecond: all other players are weaker than me. Rank restriction is from 14k to 8k. No handicap. I'm presently 5k on OGS and I'm looking for some relaxed games. This could sound rude, so I added another feature to balance that. \n\nThird: I'll leave my comments in the Malkovich log for my opponent to read after the game is done. Not exactly a teaching game but a way to share some knowledge with someone weaker than me. \nMalkovich log is normally hidden to the opponent until the end of the game. Other people can see it though. So it's not a secret log: it's a public log visible for all but one. \n\nSince it's a round Robin, other players will fight also between each other. I have no special rules for that.\nFive players. Four ranked games each. One round. Start when full.\nI hope this could be an interesting exchange.",
